TYPE EJECTOR FOR COMPOSING MACHINES.

Application filed April 27, 1925. Serial No. 26,068.

It is another object of my invention to" provide a devicewhich will receive fromthe type chute of a composing machine, multigraph as well as other standard type a' chase or individual tubes.

It is still a further object of my invention 1 to provide a device which will, without clogging the channels or breaking the type, receive and eject it'at any rate up to 1300 a minute, which is far in excess of a keyboard ,operators capacity at the present time. My device, capable of operation at this excessive speed, "eliminates all danger of'typetransposition which is so common in the slower operated machines. 1

Other important. and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims." 1

- Referring to the accompanying drawings for a detailed description'of the form of embodiment of my invention illustrated therein, then'umeral 1 designates a casting having a fiatbase from which there projectsupwardly a side sup/part3. iroject for the purpose of ejecting it laterally into ing upwardly from the middle portion of the base 2, and integral with the side support 3, is a web 4 which is turned at. its upper end to form a horizontal bearing 5 for a pulley shaft 6. I (See Figures 4 and .6.) From this bearing 5 a web 7 inclines upwardly along the side support 3 with which it is integral, toa cylindrical boss 8 that forms a bearing for a transverse shaft 9 for a purpose to be hereinafter described." See Figures2 and 7.)

Threaded on the inner end of the shaft 6 to promote ease of assembly, is apulley 10 to receive a cable (not shown) by means of which the pulley may be. driven from asuitable; motor. Secured to the outer face of the pulley 10 a short distance from its center, is a crank pin 11 to whicha connecting rod l2 is pivotally attached; Fast on the transverse shaft 9 a gear 18 to theouter face of which there is secured a disc 14 hav ing a crank end to which the free end o f the connecting rod 12 is pivotally secured by a pin 15. The throw of ,this connecting. rod 12 is adjusted to oscillate the gear 15, and through it the shaft 9, when the pulley 10 is rotated. -(See Figure I. a

. Inclining sharply upward from the. boss 8, and integral'with the-sidesupport 3, is a web 16.- Formed onthe outerupper'end -of this web is a cylindrical boss" 17 which forms a bearing for a; transverse hinge pin 18 for a swinging yoke 19' that terminates at its lowerend in a cylindrical boss 20 which forms a bearing for atransverse shaft 21. (See-Figures"1, 2,16 and 7.) Fast on the inner end of the-"shaft 21 is a gear 22 which meshes with the gear 13 foroscilerably made of metal, is a resilient" disc such lation by it. -T-he gear 22 is yieldingly held as the rubber disc 27 These discs 27, 27 project a slight distance into a vertical channel 28 between twoup'per elongated members 29, I

29 and two bottom pieces 30, 30 which form that These members 29, 29 and and pieces 36, sozwhich form the channel :28

are firmly secured to tie outer fee of the side support 3 of the casting, and are curved at their adjacent ends to conform to the contour of the discs 27, 27 which project b tween those ends a slight distance into the channel for a purpose soon to be described. (See Figure 1.)

Suitably secured upon the top of the side support 3 of the casting 1, are two rectangular metal-plates 31, 31 which are recessed at their middle portions to form, when secured together by transverse screws 32, .32, a type receiving block. The middle recessed portions of the plates 31, 31 form together a central vertical groove 33 that extends down through the block which the plates form, to receive twotype chutes 34, 34 whose upper ends are directlybelow two delivery chutes 35, 35 that receive type from a magazine not shown. At their lower ends the type chutes 34, 34 are spirally turned a suflicient amount to change the position of the type passing through them, 90 degrees before entering the channel 28 below. A. multi raph type, which is a short thick type as shown in Figure 5, must be turned edgewise or the narrow way topass throughthe chutes 34, 34 in the type receiving block without clogging it up.

Applied to the outer surfaces of the elongated members 29, 29 and the bottom pieces 30, 3O isian elongated strip such as the glass strip 36 to close the open side of the channel 28. The glass strip 36 is held in position against the members 29 and 30 by the outer ends of a yoke piece 37 through the central portion of which, and through an opposite hole in thecasting, a screw 38 is inserted.

This screw has an outer removable head 39 for pressure against the yoke piece 37' when the screw is drawn inwardly by a helical spring 40 surrounding its inner end between its fixed head and the inner surface of the side support 3 of the casting The leg 41 of the yoke piece is turned at a right angle for pivotal attachment to a slotted block 42 secured to the side support 3. The yoke means just described will yieldingly hold the glass strip 36 over the channel 28. (See Figures 1and2.) 1

A type inserted in one of the spiral chutes 34 of the type receiving block, will be turned 7 thereby 90 for proper entrance into the channel 28, through which it falls to the rubber discs 27, 27 where its descent is momentarily arrested. hen the type is caught between the discs 27,27, they are timed to be oscillated by the pulley means hereinbefore described to force it into a channel block for lateral'e ectment therefrom by means soon to be described. Referring to Figure 6, this channel block comprises a vertical member 43 secured at its-lower end by a screw 44 to the side support 3, and a rectangular 'end member 45 securedby a screw 46 in a recessed portion of said-side support. The incircular recess 47 for a crank disc 48 fast on the outer end of the pulley shaft 6. (See Figures 1 and 4.) Inclining upwardly from this circularrecess 47 to the inner surface of the rectangular channel block member 45 is a pilot-block groove 49 which is also formed in said side support 3. A tapering recess 50 is formed in the side support 3 around the groove 49 to permit a free reciprocating movement therein of an'ejector arm 51 hav ing an inwardly projecting pin 52 that enters a hole in a pilot-block 53 slidable in the groove 49, and formed at its rear end with a hole through which a crank pin 54 on the disc 48 projects. (See Figure 1.)

lVhen the disc 48 is rotated by the pulley means hereinbefore described, the curved end of the ejector arm 51 will be intermittently forced a sufficient distance between the channel block members 43 and 45 to eject through their recessed portions the type which the rubber discs 27, 27 have permitted to descend between them. W henengaged by the outer curved end of the ejector arm 51, the type will be forced through the pilot recesses which fit its neck, in the channel block memhere 43 and 45, outwardly into a chaseor in dividual tubes not shown.

The rubber discs 27, 27 are timed or synchronized so that they willbe oscillated to pass a type between them on the rearward stroke of the ejector arm 51, so that when it is moved forward byv the rotation of the disc 48, the type will be in proper position between the channel block members 43 and 45 for engagement by the curved outer end.

hen a type passes between the rubber discs 27, 27, the outer one is free'to be moved slightly outwardly against the tension of the spring 23 secured between the bearing'20 which carries the disc shaft 21 and the web 7, thereby making the engagement of the discs with the type a yielding one. 7

Adapted to be removably applied to the side support 3 of the casting, over the ejector arm 51 which it serves to. retain on the crank pin 54 of the-crank disc 48, is a cover- 55.

The latter is secured to the side support 3 by thumb screws 56, 56. Formed in the in ner'surface of the cover 55-is anannular groove 57 aroundv which the crank pin 54' is adapted to travel. The cover 55 also has on its inner surface a raised portion 58 adapted to fit snugly intothe recess '50 of the side support em prevent the ejector arm 51 fromslipping off the crank pin 54:, thus dispensing with a shoulder on that pin or other meansfor firmly securing the ejector r the ejector arm 51'.
